-CAPSULE-STRIPPER.

SPECIFICATION forming part of Letters Patent No. 270,716, dated January 16, 1883.

Application filed March 30, 1882. (N model.)

To all whom it may concern:

Be it known that I, LOUIS J. WOHNLICH, of Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Machines for Stripping Off Capsules; and I declare the following to be a full, clear, and

exact description of the same, such as will enable others skilled in the art to which'it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention consists in the combinations of devices and appliances hereinafterspecified,

- and more particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of an apparatus embodying my invention.

Fig. 2 is a plan view of a part of thesame.

constructed as to move backward and forward capsules are to be stripped.

on the bars B and G.

E is an upright movable plate secured to the plate D. The plate E is provided with an upright groove, E.

E is a mold-plate, designed to be inserted in the groove E, from the molds of which the E is a series of capsule-molds thereon. E are the capsules formed on their extremities.

I) is a screw, one end of which is properly secured to the plate D, working through the adjacent side of the frame A.

D is a crank for propelling the screw backward and forward.

F is an upright stationary plate secured to the bars B and C.

F is an upright plate constructed to move backward and forward on the bars B and G.

G represents a series of clasps or clamps,

composed of metallic jaws a, each fastened by a hinge, b, at one-end to ahead, 0, made ofany suitable material. and which is secured firmly to the plate F. Each jaw of the clasp G terminates in a flange, d, turned inwardly, and cut away in the center, as shown at 6, so as to fit upon and around the capsule-molds E H is a sliding shoulder or cross-head, with slots ff, which encompass the jaws a a and permit a free movement of theshoulder backward and forward upon the jaws. When the cross-headH is in its rearm ost-position, or nearest the hinges of thejaws, the flanges dof the jaws will be closed toward each other to properly clasp a capsule mold, the jaws being slightly inclined toward each other from their hinges; but as the cross-head advances it will separate the jaws, the distance between the slots ff being properly arranged for thatpurpose.

g is a rod rigidly secured at one end. to the shoulder H, said rod passing freely through the center of the head 0 and the plate F. The opposite end of the rod is firmly secured to the plate F.

I is a screw properly secured at one end to the plate F, working through the adjacent side of the frame A.

l is a crank for propelling the screw backward and forward.

In the use of this device it is evident that when the plate F, with its series of rods vg, is projected forward by means of the screw I, the sliding shoulder or cross-head. H is also projccted forward upon the jaws act of the clasps G, causing the jaws to open upon the hinges b I). The plate D,with the capsule-molds, may

then be projected forward by means of the screw D until the capsules are passed forward, so that the flanges d on the clasps G may be closed behind them. By reversing the movement-of the screw I the clasps are closed upon the capsule pins behind the capsules, when by reversing the screw D the mold-plate is drawn back, stripping the capsules from the pins upon which they are formed.

I am aware that in a.capsule-stripping machine the mold-plate has been advanced by mechanism similar to that employed by me to engage the molds between spring clutch-bars, and then retracted to cause the clutch-bars to strip the capsules from the molds, and I do not claim such a machine, broadly.

hat I claim is l. The combination, with the stationary clamps adapted to clasp the molds, ofthe crossheads arranged to move back and forth between said clamps, and means for operating said cross-heads, substantially as described.

2. In a capsule-stripping machine, the combination,with the mold-plate and molds and means for advancing and retracting the same in straight lines, of the stationary clamps and means for opening and closing said clamps independently of the molds, substantially as described.

3. lfhe combination, with the clamps composed of the hinged jaws to and the stationary plate to which said jaws are hinged, of the cross-heads H, provided with slots embracing [5 said jaws, rods g, movable plate F, and means for advancing and retracting said plate, all connected and operating substantiallyas described.

In testimony whereof I sign this speciiica- 20 tion in the presence of two witnesses.
